Vintage Large Hard Disk Head Assembly Siemens Nixdorf Mainframe NEW OLD STOCK

I am wondering if this hard disk drive head assembly could possibly be for the Entrex 480 system...or is it "too new", with the date of April 12, 1982?



Up for sale is a Vintage Large Hard Disk Head Assembly Siemens Nixdorf Mainframe NEW OLD STOCK.  This appears to be NEW OLD STOCK. look at the pics. Seems like it was headed back to Siemens Nixdorf as that was where it is addressed on the box. If you know who makes this let me know. Look at all pics and offer accordingly.

eBay Auction Archive

Here we have a very collectable "Magnetic Tape" that was used on the ENTREX & NIXDORF

16 Bit 280, 380 & 480 Mini Computers back in the early 1980's.

This is a brand new unopened 200' tape that was used to backup data and programs way back in the day.


Very rare and hard to find still in the unopened factory sealed package.
The tape has a date code of 8521 - 1985 21st week  (33 years old).


It has a yellow "write ring" in the back to enable writing or if you remove the label it was write protected.

The black piece on the top of the tape is the locking dust cover and had a hook on it to hang it in tape storage units.

Very nice and interesting piece of vintage computer history.

Limited Edition Serigraph Print "Entrex Building" by C.J. Yao!

Well, it's not about any Entrex system, per se, but it is likely a picture (or painting, if you can believe that) of the Entrex building in Massachusetts back in the day.  It seemed mildly worthy of historical archive on this site, anyway...

Vintage Entrex 480 DCC D116 mini computer, DG nova clone ("The Lost Entrex")

In the words of the original seller of this auction, May 2017:

Vintage Entrex 480 Mini Computer

There is not a lot of information in regard to this computer on the internet although  google search will net some information.   

This is the computer component of a larger Entrex data entry system from the early 70s.  This CPU is based on if not build by Digital Controls Corporation(DCC).   

It is physical appearance if very similar to the DCC D-116 (see the last photo).  Indeed it contains a DCC CPU board and a DCC Synchronous communications controller board.  

It also contains a Entrex Disk controller board and an Entrex Tape controller board.  

Finally it has 4 Entrex Core memory boards of 8K each.   Most likely a very rare computer.

Vintage Circuit Board Entrex 307-044-500-202 edac

The pictures aren't much to look at, with poor focus, but you can make out that it's a connector of some kind.  And this "badge" hanging off of the middle wire bundle which appears to say "ENTREX".

Was it a board connector for this system?  Maybe we'll never know.  Unfortunately, I didn't buy this either.
